Gas work in an early-1900s town
Mount Rainier began as a streetcar suburb right on the District line, and much of the town is a National Register historic district full of Craftsman homes and Sears kit houses. The median home was built in 1952, one of the oldest housing stocks in the county. Gas piping in these houses has usually been reworked several times as heating, cooking and hot water changed over the decades, leaving a mix of old threaded pipe, newer runs and sometimes abandoned stubs.
Washington Gas serves Prince George's County, and BGE serves some areas, so confirm the company on your gas bill. Although the town borders Washington, it is in Prince George's County, so county and WSSC rules apply, not the District's. WSSC Water issues permits for and inspects plumbing and all natural gas and LP gas installations in the county, and furnace and gas water heater replacements must be done by a plumber or gasfitter holding a WSSC license. The city's Code Compliance Department issues city building permits and notes that some permits come from the county, so a remodel that moves a gas range may involve more than one office.
Patch, extend or rerun?
| Situation | Usual approach | Paperwork |
|---|---|---|
| Leak at a single old valve | Replace the valve and retest | Plumber advises |
| Abandoned stub in the basement | Cap correctly or remove | Plumber advises |
| New gas range in a remodeled kitchen | New branch with shutoff | WSSC permit; city permit if the remodel needs one |
| Repeated leaks along original pipe | Replace sections or the full run | WSSC permit and inspection |
Signs to watch for
- Any gas odor: leave the house, then call 911 and Washington Gas
- A hiss at a basement valve or the meter
- Lazy yellow flames on the stove or water heater
- Soot on the chimney thimble or around a vent connector
Timing and seasonal notes
Older houses can be drafty, and on the coldest nights the furnace and water heater run nearly nonstop, which is when a weak line or a balky regulator shows itself. Early fall is a sensible time to have gas connections looked at. If you're planning a kitchen or basement renovation, bring gas piping into the plan early so permits and inspections fit the schedule.
